Let the total number of steps in the escalator be x. The escalator moves at a constant speed given by Speed of escalator = (x − 8)/37.5 = (x − 14)/28.5 The above equation may be solved as follows. 28.5 (x − 8) =37.5 (x escalator = (33 − 8)/37.5 = (33 − 14)/28.5 = 1/1.5 steps/second. Time to reach top = Total Steps / Speed = 49.5 seconds.
